Live Ip and Public Ip are both the same. This is used in a WAN environment, each router receives a Live Ip, which is updated after some time. For the end user, there is no public Ip.PPP used for real-time addressing.
Non-Live or Private Ip, both are used interchangeably. This IP is used inside the network (LAN environment), in which each node receives one specific private ip. DHCP is used for addressing without using Ip.
NAT is mainly used to translate non-Live (Private) Ip to Live (Public) Ip.
